New Computer

I have had Norton Antivirus for several years, and have been renewing my subscription every year.  The last renewal was this past March.  The computer I was using had Windows Xp Professional on it.  That computer crashed and I ended up buying a new computer with Windows 7 on it.  The disc I had with the Norton Antivirus on it will not load on this new computer, so I went to my account and tried downloading from there, but I keep getting notices saying my trial period is just about over and I have to purchase.  I don't want to lose the last six months of my current subscription and start over.

 

Any ideas as to what I can do?

 

Thanks,
